Ireland prop Andrew Porter has defended himself against accusations of foul play after Antoine Dupont suffered a season-ending knee injury during France's Six Nations win in Dublin on Saturday. Ireland still have a slim chance to win the Six Nations -- which would be an unprecedented third successive title -- but they would need an unlikely set of results in the final round of games.

France will try to win the Six Nations without its talisman after captain Antoine Dupont ruptured cruciate ligaments in his right knee at the weekend.

France moved into pole position for the Six Nations title on Saturday, withstanding an early Antoine Dupont injury to thrash Ireland 42-27 with a blistering second half that dealt a likely fatal blow to the hosts' hopes of a record third title in a row.
